DETAILED DESCRIPTION

The present disclosure relates to audio programming such as that provided via radio or television, and more specifically to a service that facilitates consumption of such audio programming.

FIG. 1 is a system diagram illustrating a portion of a system 100 that supports wireless devices operating according to some embodiments disclosed herein. The system 100 includes multiple wireless devices residing within in a wireless personal area network (PAN) 105. Wireless PAN systems generally replace cumbersome cabling used to connect peripheral devices or mobile terminals by providing short distance wireless links that allow connectivity within very narrow spatial limits (typically, a 10-meter range). Various technologies can be used to implement the components of the system 100 as should be appreciated. A non-limiting list of technologies which can be used to implement wireless PAN 105 includes Bluetooth®, IEEE 802.15.1, 802.15.4, Zigbee, and Wireless Universal Serial Bus™. For some wireless PAN technologies, a wireless device registers with or joins a wireless PAN 105 before transmitting or receiving on the wireless PAN 105. Wireless devices become known to one another through this registration process. However, some technologies also allow a wireless device to transmit or receive via the network without registering or joining. As used herein, “transmitting over the wireless PAN” refers to transmission by a wireless device that is located within range, or in the coverage zone 107, of the wireless PAN 105, regardless of whether the transmitter has become a member of the wireless PAN 105. Similarly, “receiving over the wireless PAN” refers to reception by a wireless device that is located within range of, or in the coverage zone of, the wireless PAN 105, regardless of whether the receiver has become a member of the wireless PAN 105.

Wireless devices residing within the wireless PAN 105 may include, for example, one or more wireless network audio broadcast devices 110, one or more wireless network audio listening devices 115, and one or more wireless network mobile computing devices 120. A wireless network audio broadcast device 110 outputs a digital audio stream over wireless PAN 105 for consumption by a wireless network audio listening device 115. Using techniques described herein, an audio intermediary module 125 within wireless network mobile computing device 120 acts as an intermediary to facilitate this consumption. For example, the audio intermediary module 125 may provide a mechanism for a user to select a wireless network audio broadcast device 110. In some embodiments, the audio intermediary module 125 forwards the selected digital audio stream to a wireless network audio listening device 115. In other embodiments, the audio intermediary module 125 provides identifying information so that the wireless network audio listening device 115 can receive the digital audio stream directly from the selected wireless network audio broadcast devices 110.

The intermediary techniques disclosed herein can be particularly advantageous to wireless network audio listening devices 115 that are not capable of receiving, or are not programmed to receive, broadcasts via the wireless PAN. By having the wireless network mobile computing device 120 receive and forward broadcast audio streams, such legacy listening devices nonetheless benefit from digital audio broadcasts. Similarly, the intermediary techniques disclosed herein can be particularly advantageous to wireless network audio listening devices 115 that are not capable of exchanging, or are not programmed to exchange, capabilities information with a wireless network audio broadcast device 110. Such legacy listening devices can nonetheless render audio being broadcast by a wireless network audio broadcast device 110 once the wireless network mobile computing device 120 receives identifying information from the wireless audio netowork audio broadcast device 110 and provides that information to the legacy listening device 115.

A wireless network mobile computing device 120 may take the form of a cellular telephone, a tablet computer, a notebook computer, a media player, a game station, or any other computing device that is mobile and supports a wireless PAN connection. In the example shown in FIG. 1, the wireless network audio broadcast device 110-T takes the form of a television and the wireless network audio broadcast device 110-R takes the form of a radio receiver but other sources of digital audio are also applicable. In some embodiments, a wireless network audio broadcast device 110 receives programming on a media channel and outputs audio associated with this programming. However, in other embodiments, a wireless network audio broadcast device 110 plays back stored audio (e.g., a digital jukebox). In the example embodiment of FIG. 1, the wireless network audio listening device 115 takes the form of headphones, but the wireless network audio listening device 115 may make other forms, such as a single-ear headset or speakers. As another example, the wireless network audio listening device 115 make take the form of a hearing aid, using one of a variety of coupling technologies such as telecoil. A wireless network audio listening device 115 may support mono or stereo sound.

FIG. 2 is a messaging diagram showing interaction between various components of the system 100 in an example scenario, according to some embodiments disclosed herein. In this scenario, the audio intermediary module 125 within the wireless network mobile computing device 120 (FIG. 1) discovers a wireless network audio broadcast device 110, receives a digital audio stream from the wireless network audio broadcast device 110, sand forwards the digital audio stream on to the wireless network audio listening device 115. Another scenario will be discussed later, in which the audio intermediary module 125 does not act as a forwarder, but instead provides the wireless network audio broadcast device 110 and/or the wireless network audio listening device 115 with information that allows the wireless network audio listening device 115 to receive the digital audio stream directly from the wireless network audio broadcast device 110.

In the example scenario shown in FIG. 2, the wireless network audio broadcast device 110 provides a broadcast digital audio stream 205 independent of any particular request for the stream 205, and independent of devices already connected to the wireless network audio broadcast device 110. In some embodiments, any listening device may discover the broadcast digital audio stream 205 by listening to the wireless network audio broadcast device 110. In some embodiments, the wireless network audio broadcast device 110 transmits to a predefined broadcast address or set of broadcast addresses.

In some embodiments, the audio intermediary module 125 listens for the broadcast digital audio stream 205. Having found at least one broadcast from at least one wireless network audio broadcast device 110, the audio intermediary module 125 sends a query message 210 to a wireless network audio broadcast device 110 in order to obtain an identifier and a description of the device's capabilities. The wireless network audio broadcast device 110 responds with a message 215, which includes the requested information. In some embodiments, wireless devices are identified using frequency, time slot, clock, device address such as a media access control (MAC) address, or a combination thereof. Furthermore, the capabilities returned in the message 215 may include a device type, category, or supported profiles.

In some embodiments, query message 210 may be received by multiple wireless network audio broadcast devices 110, and then multiple responses may received by audio intermediary module 125. The responses 215 may serve to enable audio intermediary module 125 to discover the available broadcast digital audio streams 205 in lieu of listening for broadcast digital audio streams for the purposes of discovery.

Once the broadcast digital audio stream 205 has been discovered via the capabilities exchange of messages 210 and 215, the audio intermediary module 125 residing in the wireless network mobile computing device 120 forwards the digital audio stream 205, as digital audio stream 225, to the wireless network audio listening device 115. Whereas transmission of the digital audio stream 205 involves a broadcast by the wireless network audio broadcast device 110, transmission of the digital audio stream 225 typically involves a connection between the audio intermediary module 125 of the wireless network mobile computing device 120 and the wireless network audio listening device 115. In some embodiments, the wireless network audio broadcast device 110 is capable of providing multiple streams, and in such embodiments, a stream identifier or a program identifier may be used by audio intermediary device 125 in order to identify and select the appropriate digital audio stream to forward to wireless network listening device 115.

In the embodiment shown in FIG. 2, transmission of the digital audio stream 205 occurs prior to and independent of the capabilities exchange. In another embodiment, the wireless network audio broadcast device 110 may automatically begin transmission of the digital audio stream 205 after the capabilities exchange has occurred. In still another embodiment, the audio intermediary module 125 makes a specific request (not shown) to the wireless network audio broadcast device 110 to start the transmission of the digital audio stream 205.

The message exchanges shown in FIG. 2 may be implemented in various ways depending on the underlying technology, as may be appreciated. In a Bluetooth® or IEEE 802.15.1 implementation, the capabilities exchange of messages 210, 215 may utilize extended inquiry, inquiry response, and extended inquiry response (EIR) and/or service discovery protocol (SDP) mechanisms. The inquiry, inquiry response and EIR mechanisms may further be used to discover one or more available broadcast digital audio streams in lieu of listening for broadcast digital audio streams for the purpose of discovery. An inquiry response message may include the clock, device address, and Class of Device (e.g., TV, phone, personal computer, etc.). As another example, an extended inquiry response packet may add device name and other information such as the services supported by the wireless network audio broadcast device. In some embodiments, the services supported may indicate support for the discovery, intermediary, and forwarding techniques disclosed herein. In embodiments that do not support an extended inquiry response, the capabilities exchange may involve a partial connection between the audio intermediary module 125 and the wireless network audio broadcast device 110 to discover device identity and a full connection to discover device capability.

FIG. 3 is another messaging diagram showing interaction between various components of the system 100 in another example scenario, according to some embodiments disclosed herein. In this scenario, the wireless network mobile computing device 120 (FIG. 1) does not act as a forwarder for a digital audio stream, but instead provides the wireless network audio broadcast device 110 (FIG. 1) and/or the wireless network audio listening device 115 (FIG. 1) with information that allows the wireless network audio listening device 115 to receive a digital audio stream directly from the wireless network audio broadcast device 110. The digital audio stream broadcast by the embodiment of FIG. 3 is similar to that discussed above in connection with FIG. 2. That is, the wireless network audio broadcast device 110 provides a broadcast digital audio stream 305 independent of any particular request for the stream 305, and independent of devices already connected to the wireless network audio broadcast device 110. In one embodiment, the audio intermediary module 125 of the wireless network mobile computing device 120 listens as described herein for the broadcast digital audio stream 305. Having found at least one broadcast, the audio intermediary module 125 learns the identifier of the audio broadcast device through the capabilities exchange of messages 310, 315, which are analogous to the messages 210, 215 discussed earlier in connection with FIG. 2. In another embodiment, audio intermediary device 125 may discover one or more audio source devices 110 using the same mechanism used to perform the capabilities exchange involving messages 310 and 315. Having discovered the wireless network audio broadcast device 110 through messages 310, 315, the audio intermediary module 125 sends a message 320, which informs the wireless network audio listening device 115 of the presence of the wireless network audio broadcast device 110. The message 320 includes sufficient information for the wireless network audio listening device 115 to begin receiving the broadcast digital audio stream 305 being transmitted by wireless network audio broadcast device 110. In some embodiments, the message 315 includes a network or MAC address, frequency, a time slot, a clock, or a combination thereof. In some embodiments, the wireless network audio broadcast device 110 is capable of providing multiple streams, and in such instances message 315 may include a program or stream identifier.

The scenario of FIG. 2 involved wireless network mobile computing device 120 acting as an intermediate forwarding device. In contrast, the scenario of FIG. 3 involves wireless network audio listening device 115 directly receiving the broadcast digital audio stream 305 from wireless network audio broadcast device 110. This typically would allows wireless network mobile computing device 120 containing audio intermediary module 125 to not consume power as a result of receiving and retransmitting the digital audio stream. However, the scenario of FIG. 3 does require that wireless network audio listening device 115 be capable of directly receiving a broadcast digital audio stream. In some embodiments, wireless devices may take on master and slave roles. For example, the wireless network audio broadcast device 110 may act as a master when transmitting the digital audio stream 325, while the wireless network audio listening device 115 receives as a slave. As another example, the wireless network mobile computing device 120 may simultaneously act as a slave to receive from the wireless network audio broadcast device 110 and as a master to transmit to the wireless network audio listening device 115.

As noted above in connection with FIGS. 2 and 3, the audio intermediary module 125 may act as a forwarding intermediary, or may facilitate a direct connection between the wireless network audio broadcast device 110 and the wireless network audio listening device 115. Some embodiments of the audio intermediary module 125 support both behaviors, and dynamically select between the two based on operating conditions. For example, the audio intermediary module 125 may elect to operate as a forwarder when the wireless network audio broadcast device 110 is closer to the wireless network mobile computing device 120 than to the wireless network audio listening device 115. As another example, the audio intermediary module 125 may elect not to operate as a forwarder when the charge on its battery drops below a predefined threshold. As yet another example, the audio intermediary module 125 may elect not to operate as a forwarder when the wireless network audio broadcast device 110 and the wireless network audio listening device 115 are located on the same subnet or piconet.

FIGS. 4A and 4B each illustrate interaction between various components of the system 100 in a capabilities gathering scenario, according to some embodiments disclosed herein. In both scenarios, the audio intermediary module 125 gathers capabilities data from wireless devices 405, some of which are wireless network audio broadcast devices 110 (FIG. 1). The audio intermediary module 125 processes the capabilities to present the user with a choice of these wireless network audio broadcast devices 110. In both scenarios, a wireless PAN 105 includes five wireless devices 405 other than the wireless network mobile computing device 120: two televisions 405-T1 and 405-T2; a notebook computer 405-N; a game station 405-G; and a headset 405-H. In the two scenarios illustrated in FIG. 4A and FIG. 4B, different wireless devices 405 are queried.

In the embodiment illustrated in FIG. 4A, the audio intermediary module 125 exchanges capability messages 410 with all wireless devices 405 residing in the wireless PAN 105, thus discovering the presence of five wireless devices 405 residing in the wireless PAN 105. Audio intermediary module 125 then filters the capabilities information to discover the presence of wireless network audio broadcast devices 110 in general, of specific types of wireless network audio broadcast devices 110, or of specific wireless network audio broadcast devices 110. For example, audio intermediary module 125 may look generally for a device type such as “audio source” or “audio broadcast,” or may look more specifically for a device type of “television.” The audio intermediary module 125 then presents a list of the wireless network audio broadcast devices 110 to the user via a display that is integrated with or coupled to the wireless network mobile computing device 120.

In the embodiment illustrated in FIG. 4B, the audio intermediary module 125 exchanges capability messages 410 with only those wireless devices 405 that are also operating as wireless network audio broadcast devices 110. For example, the audio intermediary module 125 may send a capability query that is qualified by a device type such as “audio source” or “television,” so that only the wireless network audio broadcast device 405-T1 and the wireless network audio broadcast device 405-T2 respond. In contrast, the embodiment of audio intermediary module 125 shown in FIG. 4A sends a general capability query, so that the notebook computer 405-N, the game station 405-G, and the headset 405-H also respond. In some embodiments, the audio intermediary module 125 further discovers which audio broadcast devices provide audio programming over the wireless PAN 105. That is, embodiments are contemplated in which devices produce audio for local consumption, but are not capable of, or are not configured to, provide the audio to a wireless network audio listening device 115 over the wireless PAN 105.

Regardless of whether the audio intermediary module 125 filters out devices other than audio broadcasts or specifically targets devices, the audio intermediary module 125 then presents a list of the wireless network audio broadcast devices 110 to the user via a display that is integrated with or coupled to wireless network mobile computing device 120. FIG. 5A illustrates an example user interface 500A presented by the audio intermediary module 125 (FIG. 1), through which a list of discovered wireless network audio broadcast devices 110 (FIG. 1) is presented to a user of the wireless network mobile computing device 120 (FIG. 1). While the term list is used herein, no particular arrangement such as a linear arrangement is implied. The list 505A corresponds to the wireless network audio broadcast devices 110 discovered in the scenario of FIGS. 4A and 4B, and thus includes entries for the television 405-T1 and the television 405-T2 (but not for the notebook computer 405-N and the game station 405-G). After the user makes a selection 510A of one of the wireless network audio broadcast devices 110 on the list 505A, the audio intermediary module 125 begins listening to a digital audio stream.

Entries in list 505A may include various types of information that may aid the user in making a selection. For example, a list entry may include information such as a name or description of the wireless network audio broadcast device 110 (e.g., “Bar TV Left,” “Bar TV Right”). In embodiments in which the digital audio stream provided by a wireless network audio broadcast device 110 is associated with a media channel or program, a list entry may also include a name or description of the media channel or program (e.g., “NBC”, “Univision”).

FIG. 5B illustrates another example user interface 500B presented by the audio intermediary module 125. User interface 500B presents not only a list 5008 of discovered wireless network audio broadcast devices 110 (FIG. 1), but also information about the digital audio streams associated with each wireless network audio broadcast device 110. In this example, a single wireless network audio broadcast device 110 (“Bar TV Left”) offers two different streams: “NBC” and “NBC Spanish.” User interface 500B allows the user to select, from a list 505B, a particular stream offered by a particular wireless network audio broadcast device 110. After the user makes a selection 510B of a stream from list 505B, audio intermediary module 125 begins listening to the selected digital audio stream.

While some embodiments of the audio intermediary module 125 allow a user to choose from multiple wireless network audio broadcast devices 110, other embodiments may make a default choice without user intervention. For example, the audio intermediary module 125 may select the broadcast source that is closest to the wireless network audio listening device 115, or may select a broadcast source based on the type of device or programming (e.g., television preferred over radio, English language programming preferred over Spanish language programming, etc.).

As described herein, the audio intermediary module 125 allows a user to choose a wireless network audio broadcast device 110 for listening from a list of available broadcast sources. The audio intermediary module 125 may also provide a mechanism which allows a user to select from among multiple wireless network audio listening devices 115. Such an embodiment may be useful in a scenario where two headsets are present in the same room as the user, and he wishes to listen to a wireless network audio broadcast device 110 while in that room. Also, though not specifically illustrated, the audio intermediary module 125 may also provide a user interface or other mechanism for a user to stop or disable the digital audio stream provided by a wireless network audio broadcast device 110 to a wireless network audio listening device 115.

Notably, in some embodiments the transmission of a digital audio stream over a wireless PAN 105 by a wireless network audio broadcast device 110 is independent of audio provided to a local consumer. That is, a television 110-T transmitting a stream to a wireless network audio listening device 115 may or may not be reproducing that same stream using speakers colocated with the television. A television 110-T may be reproducing a different stream instead, or may not be producing a stream at all, for example, if the sound is muted. Thus, a television 110-T may be playing the audio associated with one TV program over local speakers and sending the sound for another TV program to a wireless network audio listening device 115. Furthermore, a given wireless network audio broadcast device 110 may support simultaneous transmission of multiple digital audio streams.

FIG. 6 is a flow chart illustrating operations of audio intermediary module 125 within the wireless network mobile computing device 120 (FIG. 1), according to some embodiments disclosed herein. Alternatively, the flowchart of FIG. 6 may be viewed as implementing various steps of a method to discover an audio broadcast source that is transmitting a digital audio stream and to facilitate reception of the audio stream by an audio listener, as performed by the wireless network mobile computing device 120.

At box 605, the audio intermediary module 125 discovers the wireless network audio broadcast devices 110 (FIG. 1) that are in the coverage zone of a wireless PAN 105. As noted above, in some scenarios the audio intermediary module 125 and/or the wireless network audio broadcast device 110 have not joined the wireless PAN 105. The audio intermediary module 125 may make this discovery through a general query of all wireless devices or a targeted query of wireless network audio broadcast devices 110. The audio intermediary module 125 may further discover additional information from the wireless network audio broadcast devices 110, such as which programs or streams are available from each wireless network audio broadcast device 110.

At box 610, the audio intermediary module 125 provides information about the discovered wireless network audio broadcast devices 110 to a user of the wireless network mobile computing device 120.

At box 620, the audio intermediary module 125 facilitates reception by a wireless audio listening device 115 of a digital audio stream that is produced by the selected wireless network audio broadcast device 110. The reception occurs over the wireless PAN 105 (FIG. 1). The process of FIG. 6 is then complete.

Alternatively, the flowchart of FIG. 7 may be viewed as implementing various steps of a method to facilitate reception of digital audio stream by a wireless audio listening device 115, as performed by the wireless network mobile computing device 120.

At box 705, the audio intermediary module 125 listens for a digital audio stream that is broadcast over a wireless PAN 105. As noted above, in some scenarios the audio intermediary module 125 and/or broadcasting device have not joined the wireless PAN 105. The audio intermediary module 125 may listen on a predefined broadcast address or set of broadcast addresses. Next, at box 710, the audio intermediary module 125 identifies the source of the received broadcast through a general query of all wireless devices or a targeted query of wireless network audio broadcast devices 110. The audio intermediary module 125 may further discover additional information from the wireless network audio broadcast devices 110, such as which programs or streams are available from each wireless network audio broadcast device 110.

At box 715, the audio intermediary module 125 provides information about the discovered wireless network audio broadcast devices 110 to a user of the wireless network mobile computing device 120. At box 720, the audio intermediary module 125 receives from the user a selection of a particular wireless network audio broadcast device 110.

At box 725, the audio intermediary module 125 facilitates reception by an audio listening device of a digital audio stream that is produced by the selected wireless network audio broadcast device 110. The reception occurs over the wireless PAN 105 (FIG. 1). The process of FIG. 7 is then complete.

FIG. 8 is a block diagram of a wireless network mobile communication device 120 according to various embodiments of the present disclosure. The wireless network mobile computing device 120 of FIG. 8 includes an RF transceiver 805, an antenna 807, a processor 810, a memory 815, and various other components contained within a housing (not shown). In this example embodiment, the audio intermediary module 125 resides in the memory 815 and takes the form of instructions executed by the processor 810.
